Matt from iZotope has said “While I know this is something we’d like to do, I have not been made aware of any timetables for such features in any of our plug-ins.”

Eventide when asked on their forum “will the AAX license be only AAX-native or will there be AAX-DSP as well? Would be nice to know while thinking about HD->HDX card upgrade.” - Their response was “We can’t make any announcements regarding AAX-DSP support at this time. We’re looking into it, but I would not purchase it with the expectation that AAX-DSP support is coming soon.”

Antares in response to an email question on the subject said “Antares is currently formulating our AAX strategy for the release of AAX plug-ins. Please check our website for coming news about AAX plug-ins. We are sorry to not be able to give you a more concrete answer at the moment.”
